belliash	1f7e14fd7a	Finally, do it the proper way. This should fix all problems with accessing class attributes, at least I hope so.	2019-05-31 10:09:19 +02:00
belliash	519f5050b7	The easiest solutions are the best. Just look for attributes in object.	2019-05-31 06:54:01 +02:00

belliash	a3a2c8b619	Allow non-static methods inside static (final virtual) classes to be called statically.	2019-05-30 12:43:54 +02:00
belliash	ba1c840009	Allow a 'final virtual' classes to be declared. ... Virtual final classes are helpful in the case someone is wrapping common functions that are static, but the common class itself cannot be instantiated.	2019-05-30 09:44:46 +02:00
belliash	3530e6ea09	Get rid of useless class_alias() builtin function.	2019-05-30 06:46:09 +02:00

belliash	a5fb8ff8be	VmClassMemberAccess() should only check access right. ... There is no need for this function to report errors. Function should have responsibility over a single part of the functionality provided. This change also corrects some error messages.	2019-05-29 15:26:31 +02:00
belliash	a6f7c6d847	Prevent $base, $parent and $this from being unset.	2019-05-29 13:45:38 +02:00
belliash	02471b4ccb	Do not install private methods from parent to subclass. ... All methods defined in superclass can be access by $this and $parent construct. There is no need to copy private methods, as they cannot be access in $this context.	2019-05-29 13:25:17 +02:00
belliash	28e18bcb4b	Attempt to fix attributes lookup and their visibility.	2019-05-29 10:45:30 +02:00
belliash	2d50a64cac	AerScript supports multiple inheritance, thus it needs to iterate through whole list of derived classes.	2019-05-29 08:52:43 +02:00
belliash	4d1c246a65	Attempt to fix methods visibility mechanism.	2019-05-29 08:17:10 +02:00

belliash	4cc7940216	Correctly identify a member.	2019-05-17 09:05:17 +02:00
belliash	55acf8111f	Assume private visibility for all class members by default. ... In most (all?) modern OOP languages class members visibility is assumed to be private and programmer has to consciously set it to public or protected. PHP has the different approach what can cause a security flaws in written scripts. AerScript will not follow this way, as it seems to be conceptually broken.	2019-05-17 08:40:41 +02:00
belliash	48ccd7fef0	Copy all attributes from base classes and emit a warning if redeclared in subclass.	2019-05-17 06:52:29 +02:00

belliash	a2fb0b9ae5	Get rid of 'parent' constant. Use variable instead.	2019-05-08 08:38:40 +02:00
belliash	07bd3ceec3	Reimplement 'parent' construct as variable $parent. ... This commit also adds new controls to variables, which prevents from re-assigning a value when set. Thanks to that, both $this and $parent cannot be overwritten by using OP_STORE instruction. Other instructions still need some work.	2019-05-08 08:26:48 +02:00
belliash	17e0fb4653	Do not try to resolve constants when OP_MEMBER is next instruction on the stack.	2019-05-06 18:42:06 +02:00

belliash	7b6245572f	Remove constants management builtin functions.	2019-05-06 06:54:29 +02:00
belliash	c4b63a3018	Rename OP_LOAD instruction to OP_LOADV.	2019-05-05 09:33:06 +02:00
belliash	23900f2aed	Remove unused compiler function - PH7_CompileLangConstruct(). ... In AerScript, there are no such language constructs, that have syntax similiar to functions. If so, it is just a builtin function.	2019-05-04 18:53:11 +02:00
belliash	b36510943d	Implement 'define' statement for defining constants globally.	2019-05-04 17:08:09 +02:00
belliash	ab8bf48485	Make constant declarations local. ... There are several changes in this commit: * first of all constants declared by 'const' statement should be local (declared in current scope / frame), * constants are declared by using OP_DECLARE instruction, * OP_LOADC browses both global and local constants container, * PH7_VmRegisterConstant() allows both global and local declarations. Since this commit, there are 3 kinds of constants: 1) global 2) local (in loop, closure, method) 3) class members. Actually there is no way to declare a global constant except the built-in constants.	2019-05-04 13:45:32 +02:00
belliash	e6b7f1be2c	Always emit OP_JMPLFE as goto can be used inside a loop and frame has to be left.	2019-05-03 10:55:57 +02:00
belliash	03fc167be1	Proper implementation of so hated 'goto' statement.	2019-05-03 10:35:54 +02:00
belliash	2f3ce65289	Correct comment to if/else statements.	2019-05-02 19:03:47 +02:00
belliash	8f681d1605	Correct PH7_OP_JMPLFE debug name.	2019-05-01 20:24:37 +02:00
belliash	5a0e4667fa	More readable error message.	2019-05-01 20:09:55 +02:00

belliash	7d606cbf1d	Do not create variables automatically on each OP_CALL using VmExtractMemObj().	2019-05-01 18:19:04 +02:00
belliash	3dfa4232ba	Use VmCreateMemObj() to create $this.	2019-05-01 14:00:35 +02:00

belliash	1d6822c1e2	Allow key and value declaration inside foreach() loop.	2019-05-01 11:38:28 +02:00
belliash	a726ab795a	Throw an error if $key or $value does not exist.	2019-05-01 09:51:33 +02:00
belliash	5c1e0f0cce	Simplify the foreach() loop implementation.	2019-04-30 23:59:02 +02:00
belliash	4d8d92092e	Refactor foreach() loop. ... In AerScript, the foreach() loop is syntatically more similiar to C#, than PHP. However the optional '$key => $value' construct is still available, because arrays in AerScript are still a hashmaps.	2019-04-30 23:38:59 +02:00
belliash	1156519af6	This is a compiler task to fill key and value variables names.	2019-04-29 11:44:17 +02:00
belliash	62c315da9e	Call to undefined constant should lead to an error.	2019-04-28 21:44:48 +02:00
